1) Numbers that are the leaves on the first stem associated with $3000
Answer A) 13
2) Shape = Right skewed.
Median = (35+1)/2 th value =18th value= $2200 which is the value for United Arab Emirates
Center = $2200 of United Arab Emirates
Variability = High
3) United states is the high outlier.
4) The distribution is Right-skewed, with a single high outlier (United States). There seem to be two clusters of countries. The center of the distribution is about $2200 spent per capita. The distribution varies from about $2200 spent per capita to about $2300 spent per capita.
